Our bearings are designed to meet the requirements of the many unique applications that our rapidly changing world demands. If you have a product design that requires just the right bearing to optimize its performance, you have come to the right place.
Our bearings are used in automotive applications for everything from engines to door hinges, as well as in infrastructure and transportation applications such as bridges and helicopters. They are also used in products like door rollers, office chairs, copy machines and kitchen appliances. We have the bearings to meet your needs, including custom products developed specifically for your applications.
Tribology is derived from the Greek word “tribos” and it refers to the physical and scientific analysis of friction, wear, and lubrication when physical objects move. Machines always have parts that are subject to friction, making them susceptible to wear and other problems. To provide solutions for these challenges, Daido Metal was quick to establish its tribological approach with a combination of bimetal technology, precision processing technology, and surface treatment technology.
Bimetal refers to a composite material made by bonding one of a variety of special bearing layers onto a plate steel base. Daido Metal’s atomic-level bonding technology includes sintering, pressure welding, casting, and impregnation. We manufacture bimetals of all characteristics, using copper alloys, aluminum alloys, polymers, and other materials. The development of these bimetal materials is the foundation of our high-quality bearings and the main reason the Daido Metal brand is so well respected around the world.
Bimetal materials must undergo forming technology to produce high-performance bearing products. Extremely precise machining is required at this stage, whether it’s press cutting, press working to form parts into half-bearings or cylindrical shapes, or finishing to optimal thickness. We design and manufacture our own press molds and dedicated machinery in-house. We employ technology accurate to the micron level, allowing us to produce high-quality bearings with consistent reliability.
Smooth motion depends on the condition of the surfaces where friction occurs. With the overlay covering, the bearing layer plays a crucial role. Daido Metal continues to develop new overlays and improve production methods, and established a surface treatment technology that creates uniform and highly precise films. We continue to engage ourselves actively in developing new surface treatment technologies.
